The ever-reliable Wiki source says that the 2009 stock is 2.68m wide
and the 1973 stock 2.629, so the 2009 stock is apparently 5cm or 2"
wider. It also says that, "Unlike the 1967 Tube Stock, the trains
are built 40 millimetres (1.6 in) wider to take advantage of the
Victoria line's slightly larger than normal loading gauge compared
to the other deep level tube lines."

Unfortunately, the unreliable Wikipedia has the 1967 stock as 9' 0
1/16" which would be 2.74m wide. Also unfortunately, it is the only
source I can find for 2009 stock details.

The possibly more reliable TfL site says the 1967 stock is 2.64m wide,
and the 1973 stock, 2.629m (ie, the same as Wikipedia). I wonder if the
Wiki author misread (or mistyped into his calculator) 2.64m as 2.74m?

Assuming that TfL got it right, the increase in width of Vic stock is
40mm, which is also what Wikipedia says.
